2 Save the Earth with Amorphous! What is an Amorphous Alloy? Common Metallic Alloys Crystalline alloys have periodic atomic structures. Amorphous Alloys Non-crystalline (amorphous) alloys have random atomic structures. Image chart of atomic arrangement Domain wall motion is impeded by structural defects such as grain boundaries. Local grain size and direction can be varied by post-fabrication treatments. Image chart of atomic arrangement Randam network of atoms results in lack of crystalline anisotropy. Excellent Soft Magentic Properties. Magnetic properties can be widely changed by heat treatments.

Extremely small and uniform grains, nano-crystalline (~10nm) are obtained by heat treatment of this ribbon above the crystallization temperature. This nano-crystalline structure leads to superior soft magnetic properties than amorphous alloys. It was commonly known that magnetic properties are deteriorated with decrease of grain size. Contrary to his common understanding, FINEMET achieves excellent soft magnetic properties with nano-order crystal grains. Microstructure of FINEMET

5 Metglas Brazing Foil (MBF) Features 100% alloy foil (environmentally-friendly with no binder) Foils adhere to joint area. Instant melting and superior wetting and flow. Easy to etch and stamp. Smooth surface after joining. Major Applications Automotive, Catalytic Converter, Heat Exchanger, Honeycomb Body, Aerospace, Mechanical Equipment, Tube Material Brazing, Carbide Alloy, Tool Steel, Rainforcement Brazing Foil Free from Organic Binder As conventional Ni-based brazing alloys are too brittle to be rolled into foil, they previously were utilized in powder filled paste with resin binders and applied to the joint part, whose process was time and labor consuming. On the other hand, Metglas brazing foils can be easily applied in joint parts as they are thin and ductile metallic foils. Easy metal joints can be obtained without using binder paste.
